Retro-Mutagen Profile

Retro-Mutagen aka Retro Mutagen or RetroMutagen, is a weapon of the Ninja Turtles. This is an orange substance that was created by Donatello, which serves as a cure for the effects of the Mutagen. Retro-Mutagen debuts in The Lonely Mutation of Baxter Stockman.

Origins

After the mutation of Kirby O'Neil into Kirby Bat occurred, Donatello became determined to create Retro-Mutagen to cure his mutation and also to cure other mutants. After months of attempting to create Retro-Mutagen out of the Mutagen, Donatello had failed until the time came that the Ninja Turtles discovered that April O'Neil was half human and half Kraang. After this discovery, Donnie figured that April might have an immunity to the Mutagen, which made him use some of April's DNA to create the cure. Until many days of working in his laboratory, Donatello had finally created Retro-Mutagen.
